Item Análise de custo de edificações residenciais com placas cimentícias com pérolas de EPS e alvenaria comum utilizando o BIM(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2026-03-25) Santos, Jennifer Ataide dos; Costa, Esdras Jonathan Honorato; http://lattes.cnpq.br/6045970740812728; Limeira, Uziel Ribeiro; http://lattes.cnpq.br/2469128647529432; Almeida, Thamyrys Morgana Pontes de; http://lattes.cnpq.br/8249520310546287This study presents a comparative analysis between the Lightwall construction system and conventional masonry applied to a small-scale residential building, focusing on execution costs and productivity. Through Building Information Modeling (BIM), accurate quantity takeoffs were obtained, enabling a detailed economic assessment of both construction methods. The results reveal significant differences between the analyzed systems. Although the Lightwall system presents higher material costs, its increased productivity and substantial reduction in labor demand resulted in an overall cost approximately 27.96% lower than that of conventional masonry. Furthermore, the execution time was considerably reduced, with a decrease of about 84.13%, highlighting the potential of the industrialized system in optimizing construction schedules. Based on these findings, the study indicates that the Lightwall system is an economically competitive alternative, particularly in scenarios that require faster construction processes. In this context, the research contributes to the discussion on the adoption of industrialized construction systems in Brazil, encouraging a broader perspective in decision-making within the construction sector.Item Concreto ecoeficiente impermeável com geração de créditos de carbono(2026-02-20) Lima, Esdras Márcio Araújo; Costa, Esdras Jonathan Honorato; http://lattes.cnpq.br/6045970740812728; Santos Filho, Manoel Martins dos; http://lattes.cnpq.br/8060697649276101; Manoel Martins dos Santos Filho; Silva, Joao Gilberto Teixeira; http://lattes.cnpq.br/1438396653085065; Dantas, Vinicius; http://lattes.cnpq.br/6043085975649062Given the projected growth of the construction industry until 2030 and the guidelines of the National Circular Economy Strategy (ENEC) for 2025, this research addresses the urgent need to mitigate CO₂ emissions in concrete production. The overall objective was to determine the experimental mix design of an eco-efficient waterproof concrete, partially replacing Portland cement with silica fume and incorporating a crystallizing additive, aiming to generate carbon credits through material efficiency. The methodology adopted the ABCP mix design method to produce and compare two groups: Conventional Concrete (CC) and Eco-efficient Concrete (CE) with 10% cement replacement by silica and 0.8% Penetron Admix waterproofing additive. Technological validation involved axial compression strength tests, capillary absorption, and microstructural analysis via SEM and EDS. The results demonstrated the technical superiority of CE, which reached 35.29 MPa at 28 days, an increase of 7.1% compared to conventional concrete. In addition to presenting a drastic 80.25% reduction in permeability, validated by the formation of crystals in the microstructure, the dosage strategy allowed for savings of 44.44 kg of cement per cubic meter in environmental terms, resulting in the mitigation of 0.02844 tons of CO₂/m³, which enables the generation of equivalent carbon credits. The economic analysis indicated that, although the initial cost of CE (R$ 832.97/m³) is higher than that of CC (R$ 562.36/m³), the solution is justified by its extended durability and alignment with ESG criteria, transforming technical efficiency into a financial and environmental asset for the civil construction sector.Item Diagnóstico técnico e operacional das irregularidades em sistemas de esgoto associados ao uso inadequado de caixas de gordura em um polo gastronômico da cidade de Maceió(2016-01-17) Leite , Laily Luanny Cavalcante; Santos Júnior, Micaias Antonio dos; http://lattes.cnpq.br/8493053234919220; Santos Filho, Flavio Mario Cesar; http://lattes.cnpq.br/5054607247101741; Santos Júnior; Rangel, Maria Gabriela Lira; http://lattes.cnpq.br/1386751201245014; Oliveira, Diogo Botelho Correa de; http://lattes.cnpq.br/2647295852254445This study presents a technical diagnosis of irregularities associated with the improper use of grease traps and their impacts on the performance of the sanitary sewer system in a gastronomic hub in the city of Maceió, state of Alagoas (AL), with a focus on Doutor Antônio Gomes de Barros Avenue, popularly known as Amélia Rosa Avenue, in the Jatiúca neighborhood. The study area is characterized by a high concentration of bars and restaurants, which results in significant generation of effluents with high loads of oils and fats (FOG), widely recognized as one of the main causes of obstructions in sewer collection networks.The research adopted a mixed methodological approach, combining quantitative and qualitative analyses of operational data provided by the utility company responsible for the service. A total of 417 occurrences recorded between January 2023 and October 2025 were analyzed, extracted from the operational platforms Field Service and TsOne/CRM. The occurrences were technically reclassified according to the type of service performed, probable cause, operational effect, recurrence, and compliance of building pre-treatment systems, with emphasis on the evaluation of grease traps in light of the criteria established by ABNT NBR 8160.The results indicated a predominance of sewer unclogging services, which accounted for more than 50% of the analyzed occurrences, evidencing high recurrence in certain sections and addresses. Grease was identified as the main cause of obstructions, often associated with the absence of grease traps, undersizing of existing devices, and the lack of adequate maintenance routines. It was also observed that a significant portion of the irregularities was not formally recorded in a standardized manner, characterizing technical underreporting, which compromises sanitary monitoring, operational planning, and the adoption of effective preventive actions.It is concluded that the identified failures are systemic in nature and are directly related to the inadequate management of building pre-treatment systems in areas with a high density of food service establishments. These failures result in operational, environmental, and sanitary impacts on the public sanitary sewer network. The study highlights the need to strengthen inspection actions, improve compliance and resizing of grease traps, implement periodic maintenance plans, and promote greater integration among the utility company, regulatory agencies, and users as essential strategies to reduce the recurrence of obstructions and to improve the efficiency and sustainability of the system.
